  • Input module options are Mic/Line and Stereo Line.
  • Each input has a three band equalizer; phase switch; separate routing switches for the four main groups; PFL, monitor mix and solo in place; plus an overload indicator. Twelve to twenty-four input chassis are available.
  • Four master outputs controlled by individual main output faders. The outputs are transformer balanced on XLR connectors and have switchable, stereo linkable limiters; an LED indicating the action of limiting.
  • Four independent auxiliary sends from each input with separate level controls and on/off, pre/post switching to separate mix busses. The outputs are transformer balanced on XLR connectors and controlled by rotary master potentiometers.
  • Comprehensive M-S stereo facilities on the inputs, outputs and monitor chain allow decoding from M-S to L-R and L-R to M-S.
  • Four electronically balanced line level returns on jacks enable monitoring of mono or stereo sources from such as tape recorders.
  • Two monitor modules allow separate control of left and right. Monitor 1 is transformer balanced on XLRs and can be switched between all the main outputs, with PFL capable of being mixed in. Monitor 2 is the headphone output and follows monitor 1 except that PFL selection automatically overrides other selections. An M-S matrix amplifier may be inserted in the monitor path in order to decode a main output in the - M-S domain or check mono compatibility and phase cancellation when in the L-R domain.
  • A pair of meters - either PPMs or VUs - may be switched to monitor either the main outputs, auxiliaries or monitor output. The meters can be illuminated.
  • All input and output connectors are presented on one surface of the case and in line with their corresponding modules.
  • The mixer receives its power from an external DC voltage source. - Audio Developments AD100-09b power supply unit is designed to drive the mixer.
